'Good for nothing' in the Bible

And Shimei said, with curses, Be gone, be gone, you man of blood, you good-for-nothing:

Now by chance there was present a good-for-nothing person named Sheba, the son of Bichri, a Benjamite: and he, sounding the horn, said, We have no part in David, or any interest in the son of Jesse: let every man go to his tent, O Israel.
